It is good TV.It has built-in wifi.It is not a smart tv.But know smart tv s are everywhere.So we can use this tv as atv only, we cannot use this tv as computer.We can do screenmirroring( casting the mobile screen in tv) in this tv. It is a HD tv and is won’t support 3D.Normally sony tv ’s speakers are nice , they give a good sound .I advice you to buy a sony smart tv .
